explorer.exe keeps restarting

Greetings Everyone,
I am so glad i found this website, everyone seems very helpful and kind. 2 days ago i got a trojan/something that i thought Norton 2008 internet security cleaned. Guess not. after 2 days of cleaning...here's where i am.

explorer.exe keeps restarting and stopping about 20 times, then never tries to load again. If i try to manually load it, it does the same thing over and over. also i see imapi.exe do the same thing at the same time

I have to use Task manager>RUN to do anything

******* Here is the steps i have taken
1. Ran Spybot s&d
2. Ran Lavasoft Adaware
3. Ran Kaspersky Online Scan (have log) won't fix errors because was FREE scan
4. Ran ATF temp cleaner
4. Ran Ccleaner
6. Ran Registry Mechanic
---- even restored a older registry from a month ago
7. Turned off System Restore
8. Ran Msconfig, turned off everything uneeded for startup
9. Ran cmd prompt>sfc /scannow with original xp disk (it replaced a bunch of dll's)
10. Ran Windows Disk Cleanup
11. Tried all of this in SAFE MODE also
11.5 I uninstalled norton internet security and installed AVG free
12. Ran AVG virus and adware scan, deleted and fixed all
13. Every program i ran found something different, and i cleaned them all and deleted all files.
14. Finally found this website and ran HIJACKTHIS....SAFE MODE does the same thing with explorer.exe

so if anyone can assist me in deciphering this log file, i am pretty new at this. As descriptive as you can would be awesome

Not seeing anything in that log and not promising that we can get you up and running again, but let's give it a crack :).
Welcome to Daniweb :).

You must download it to and run it from your Desktop

Physically disconnect from the internet.

Now STOP all your monitoring programs (Antivirus/Antispyware, Guards and Shields) as they could easily interfere with ComboFix.

Double click combofix.exe & follow the prompts.

When finished, it will produce a log. Please save that log to post in your next reply along with a fresh HJT log

Re-enable all the programs that were disabled during the running of ComboFix..

Note:Do not mouse-click combofix's window while it is running. That may cause it to stall.

CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

Thank you so much for your time and help response. What you had me did seems to have worked!! i am up and running with my desktop intact!, and explorer.exe running. But i was hoping to continue with what you said just to make sure there isn't anything else.

I spoke to soon, Upon reboot after Combofix.exe, it worksand desktop stays. I uninstalled a few things that were obviously not working because i installed them while it was screwing up. I uninstalled all the AVG stuff and trojan hunters and all that stuff. Upon reboot, it goes back to the same thing, but if i run combofix.exe again...i will work untill i do something like install or uninstall.

7. After reboot, (in case it asks to reboot), please re-enable all the programs that were disabled during the running of ComboFix then post the following reports/logs into your next reply:

Combofix.txt

A new HijackThis log.

Merry Christmas and Happy New Year!
thanks so much for continuing to help me!
ok i did exactly as you said.

here is the new logs for both
I am doing all of this by "task manager>run" cause i have no desktop!! haha. after i run Combofix, it seems to be fine until i start uninstalling, installing or messing with firefox (profile corrupt and hacked?) i am now using IEExplorer for the first time. Also there was a couple errors while running Combofix....something like "Can't blah blah becasue of process is in use? also "cant do this and that because directory doesn't exist" on one of the files.....

No :(
because it was completely messed up.....so i had to turn system restore off. So they are all deleted. Should i delete firefox and it's profile?.....also THguard.exe is Trojan Hunter and i uninstalled the damn thing.....so why is it still there.....

what about a Windows XP repair? last resort......this is crazy.....combofix makes it work then it goes to hell again......i can't beleive this!
